Warm up very thoroughly; these hurt a bit.
Once warmed up, find a flat to moderately uphill road with no stops for at least a 7-8 minute stretch at high speed.
Begin by pedaling 30 seconds Zone 6 power (or as hard as you can, in other words). Immediately take 30 seconds easy pedaling (Zone 2 - this will feel really easy at this point, in comparison). After 30 seconds Zone 2 go back to 30 seconds as hard as possible. Repeat over and over until you have done 10 x 30-second hard efforts. This is the end of the first work set.
Spin lightly for 5 minutes. Then repeat as above for a second work set of 10 x 30-second intervals.
Spin lightly to recover for at least 10 minutes.
